Washer (Grover) from A2 A4 stainless steel available all sizes GOST 6402 DIN 127 DIN 7980 

Fixture from stainless steel in comparison with usual steel fastenings have the following advantages:

  1. Ferritic steels.
    Have pronounced magnetic properties. Are designated always by a capital letter of "F". Rather soft.
  2. Martensitnye became.

Firm, are firmer ferritic and austenitic. Can be as magnetic, and is not present. Their durability increases training with the subsequent holiday, similarly usual carbonaceous stalyam. If to compare with austenitic stalyam, then martensitny are more subject to corrosion. Their designation – "With".

  1. Austenitic became.
    These stalyakh contain about 25% of nickel and to 26% of chrome. This structure considerably increases corrosion resistance. Magnetic properties are practically absent. This group of staly is designated – "And". The most widespread group staly is considered austenitic. Such alloys have the additional digital designation indicating the chemical composition and, respectively, a possibility of application in this or that branch.
  • A1 – is applied most often in mobile and mechanical knots. As in stalyakh this type the high content of sulfur, they have the smallest resistance to corrosion and find limited application in optimum environments;
  • A2 – is steady against corrosion influence, not magnetic, nontoxical and almost not tempered. At low temperatures this look has quite high durability. A2 brand products are not suitable for application in acids or chlorine-containing environments at all (in salty water);
  • A3 – an analog of A2 steel, in addition stabilized by impurity: niobium, titanium or tantalum that increases its ability to korozziya resistance at rather high temperatures;
  • A4 – the same A2 steel, but unlike the second, about 2-3% of molybdenum add to it. Such impurity considerably increases resilience to acids and corrosion. This steel is most often used in food, woodworking, and also in the ship-building industry;
  • A5 – a pokhokhozha from A4 stalyama, but is stabilized still in addition by niobium, titanium or tantalum with various contents in percentage of the alloying additives. It in addition increases resilience to high temperatures.

Fixture from stainless steel in comparison with usual steel fastenings have the following advantages:

  • Resilience to corrosion influence
    Each type of stainless steel has to some extent high resilience to corrosion. Fixture is capable to resist corrosion in atmospheric conditions, and also can resist to oxidation in the majority of the existing acids, in alkali solution, in the chloride environment, and also under extreme conditions of elevated pressure or temperature;
  • Fire resistance
    The fasteners made of stainless steel will not melt even at the fire. They keep the properties at considerable differences of temperatures. Peeling and a rupture of an external covering of a hardware is not peculiar to stainless steel at long-term use. There is no weakening of durability even at considerable differences of temperatures. At the same time the product and stainless steel does not lose the rigidity and at very low temperatures.
  • Gigiyenichnost
    Hygienic properties of products do of stainless steel possible their application in medicine – by production of the medical equipment, the pharmaceutical and food industry. Fixture from stainless steel has almost unlimited service life, does not need special additional leaving and therefore is often the most favorable choice.
  • Durability
    Alloy is capable to maintain big physical pressure, at the same time without being deformed.
  • Excellent appearance
    The chromeplated steel does not lose an esthetic look even later a long time of operation. The shining surface of metal will never become covered by a rust. In production of high-quality goods now even more often it is possible to meet use of the chromeplated steel.

Reliability and durability
The rusted details – screws and nuts, it is quite heavy to turn off. At the same time there is a probability of damage of details or mechanisms of all equipment. With corrosion-proof bolts, screws and nuts of such problems will not arise. Such steel at the same time is much stronger, than bronze, aluminum or brass. And service life many times is more
